Real Time kernel US 13.04

Thanks Ralf for the suggestions.

Tomorrow i will experiment a little bit.
One strange thing that i don't understand is why does still compare the
webcam (on the bus 2) in lsusb even if i blacklisted the uvcvideo e
videodev drivers?

I also found a very interesting discussion about rtirq made on LAU
http://linux-audio.4202.n7.nabble.com/Re-Issue-with-the-priority-of-the-sound-cards-using-rtirq-td40952i20.html

Cheers
Nicola
